With plenty of behind-the-scenes footage, the video also includes commentary from director Zack Snyder, the actors, screenwriter David S. Goyer, costume designers and producers.

The lengthy clip touches on grounding Superman in the real world, the careful attention to every detail taken while making the film and the redesign to the famous suit.

Snyder reflects on getting rid of Superman's signature underwear-outside-of-pants look: "I probably looked at hundreds of versions with underwear. It fell by the boards because I couldn't make it consistent with the world that we were creating."

Warner Bros. and Legendary Pictures' Man of Steel, which also stars Russell Crowe, Kevin Costner and Diane Lane, opens in theaters in 3D on June 14.
